Abstract

The present invention provides 1,3,3,3-tetrafluoropropene (HFO-1234ze) copolymers comprising 1,3,3,3-tetrafluoropropene and one or more comonomers selected from the group consisting of vinyl fluoride (VF), vinylidene fluoride (VF 2 ), tetrafluoroethylene (TFE), chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), and perfluoro(alkyl vinyl ether) (PAVE), wherein said alkyl contains 1 to 5 carbon atoms, the copolymers being a fluoroplastic or a fluoroelastomer, depending upon monomer content.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A copolymer comprising 1 to 40 mol % 1,3,3,3 tetrafluoropropene, 15 to 60 mol % vinylidene fluoride, 5 to 25 mol % tetrafluoroethyene, and 15 to 40 mol % perfluoro(alkyl vinyl ether), to total 100 mol %. 
     
     
       2. The copolymer of  claim 1  wherein said perfluoro(alkyl vinyl ether) is perfluoro(methyl vinyl ether). 
     
     
       3. The copolymer of  claim 1  wherein said copolymer is a fluoroelastomer.
